While dementia typically occurs among the elderly, more and more people are starting to develop dementia in their 40s and 50s.

According to a nationwide study in 2015, 1 in 10 Singaporeans aged 60 and above had dementia. There were 28,000 Singaporeans diagnosed with the condition that year and that number is expected to rise to 80,000 by 2030. But it’s not just the older population that suffers from dementia. In 2015, there were 121 Singaporeans below aged 65 diagnosed with the condition, up from just 27 cases in 2011.

To accommodate the rising numbers, the number of dementia care places are expected to increase from 1,000 to 3,000 by 2020. But while preparations are ongoing to build a dementia-friendly Singapore, the trend continues to rise, putting you and your loved ones at risk.

The good news is that our everyday lifestyle choices may help reduce the risk of dementia.

What is dementia?

According to the National Institute on Ageing (NIA), dementia is a brain disorder that affects communication and performance of daily activities. Dementia is an umbrella term for a set of symptoms including impaired thinking and memory. The condition is often associated with the cognitive decline of ageing.

Alzheimer’s disease is a form of dementia that specifically affects parts of the brain that control thought, memory and language. Other diseases like Huntington’s Disease, Parkinson’s Disease and Creutzfeldt-Jakob disease can progress to dementia.

With Alzheimer’s being the most common cause of dementia, the following 5 tips will equip you with relevant information to help you prevent or combat Alzheimer’s.

Clock in regular exercise

Did you know regular physical exercise can reduce your risk of developing dementia by up to 50%? Exercise can also slow further deterioration in those who have already started to develop cognitive problems.

As you age, you may be more at risk of head injuries from falls, which in turn increase your risk of injuring your brain. Balance and coordination exercises can help you stay agile and avoid falls. Balance and coordination exercises include taichi, yoga, pilates or exercises using balance balls.

Opt for a healthy diet

Research suggests that making the right food choices could protect your brain function and lower your odds of getting dementia. Additionally, for a person with dementia, proper nutrition can keep the body strong and ease behavioural symptoms.

Less sugar and saturated fat. Sugary foods, refined carbs and fatty foods can lead to weight gain, putting you at the risk of further health problems such as diabetes. Diabetes has been closely linked to Alzheimer’s. Read food labels, watching out for the amount of sugar and saturated fat a product contains, and seek out healthier options.

Follow a Mediterranean diet. A Mediterranean diet is high in whole grains, vegetables, nuts, legumes, spices, oily fish, olive oil and other foods high in omega fats, while being low in red meat, refined foods and sugar. Mounting research shows that the DHA found within these healthy fats may help prevent Alzheimer’s disease and dementia. Food sources include cold-water fish such as salmon, tuna, trout, mackerel, seaweed, and sardines. You can also supplement with fish oil.

Enjoy your tea. According to a study in the December 2016 Journal of Nutrition, Health & Ageing, frequent and regular consumption of tea — whether black, green or oolong — is linked to a lower risk of dementia. It is suggested that the benefits of tea on the brain come from the bioactive compounds in tea, catechins and theaflavins, which contain anti-inflammatory and antioxidant potential and other brain-protecting properties.

Supplement your diet. Vitamin B3 and B6 are needed by the body to form neurotransmitters, making them important for the healthy functioning of the nervous system and brain. Vitamin D is a strong anti-inflammatory and immune boosting nutrient, which may help to slow the onset and development of dementia. Vitamin E has also been found to be helpful in preventing dementia diseases such as Alzheimer’s.

Stimulate your mind

If you don’t keep your body active it will start to lose its muscle and fitness. Your brain is no different.

Mental challenges help to build up the brain, making it less vulnerable to developing the lesions that can cause Alzheimer's disease. Mental stimulation can also help to slow brain deterioration in people who already have the disease.

Learn something new. Practise a musical instrument, pick up a foreign language, read a good book, take up a new hobby. The greater the novelty and challenge, the greater the benefit.

Play strategy games and puzzles. Brain teasers and riddles can give you a mental workout and train your brain to form and maintain cognitive associations. Crossword puzzles, board games, cards, Scrabble and Sudoku are all great options.

Break convention. Eat with your non-dominant hand, take a new route home, break an old habit. doing something out of your comfort zone generates new brain pathways.

Reduce stress

Persistent stress takes a toll on the brain, increasing the risk of dementia. In fact, many studies have linked anxiety with the development of Alzheimer’s, especially in people who are already at risk for the disease.

Relax and have fun daily. Make it a point to keep stress under control by intentionally spending time to relax. Find leisure activities that will relax you and do them — whether it is knitting, taking a walk in the park, yoga or playtime with your dog.

Meditate. Meditation can increase protective tissue in the brain and reduce the hormone cortisol, which has been known to increase the risk of developing dementia.

Laugh more. The act of laughing can help your body fight stress. Socialising, laughing, playing and being active helps to engage the brain and aid in preventing dementia.

Sleep well

It is not uncommon for people with Alzheimer’s disease to suffer from insomnia and other sleep problems. Research suggests that poor sleep isn’t just a symptom of Alzheimer’s, but a possible risk factor.

Researchers found that poor, disrupted sleep promotes buildup of a certain protein in the brain that can lead to impaired memory and Alzheimer’s. Getting more deep sleep, then, might be able to clear the protein burden in the brain.

Make sleep a priority by establishing a regular sleep schedule. If you've received complaints about your snoring, you may want to get tested for sleep apnoea, a potentially dangerous condition where breathing is disrupted during sleep. Being treated for sleep apnoea can make a huge difference to your sleep quality.

If insomnia is a problem, try exercising, creating a relaxing bedtime ritual, or consulting a doctor.
